Description

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of data processing, and more particularly to data display and interpretation via an overlay mechanism.

A chart or graph can be described as a type of information graphic or graphic organizer that represents tabular numeric data and/or functions. Charts are often used to make it easier to understand large quantities of data and the relationship between different parts of the data. Charts can typically be read more quickly than the raw data from which the graph is generated. Charts and graphs are used in a wide variety of fields, and can be created by hand (often on graph paper) or by computer using a charting application.

Data visualization involves the creation and study of the visual representation of data. A primary goal of data visualization is to communicate information clearly and efficiently to users via the information graphics selected, such as tables and graphs. Effective visualization helps users in analyzing and reasoning about data and evidence. It makes complex data more accessible, understandable, and usable. Users may have particular analytical tasks, such as making comparisons or understanding causality, and the design principle of the graphic (i.e., showing comparisons or showing causality) follows the task. Tables are generally used where users will look-up a specific measure of a variable, while charts of various types are used to show patterns or relationships in the data for one or more variables.

SUMMARY

Embodiments of the present invention disclose a method, a computer program product, and a system for displaying data. The method may include one or more computer processors receiving a plurality of coordinates of an overlay on a graphical data display, wherein the plurality of coordinates indicate a position and a size of the overlay.

The one or more computer processors de-emphasize at least a portion of the one or more retrieved data points. The one or more computer processors display, in the overlay, one or more retrieved data points of the graphical data display that reside within the plurality of coordinates of the overlay.

DETAILED DESCRIPTION

Information displays, such as data tables and graphs, can be highly complex and overwhelming to a user of a data analysis application. The more data points displayed on a graph, the more difficult the task of sifting through the data and creating an accurate assessment can be for the user. Embodiments of the present invention recognize that data analysis may be improved by implementing a data visualization mechanism that simplifies extracting information from complex information spaces. Implementation of embodiments of the invention may take a variety of forms, and exemplary implementation details are discussed subsequently with reference to the Figures.

FIG. 1 is a functional block diagram illustrating a distributed data processing environment, generally designated 100, in accordance with one embodiment of the present invention. FIG. 1 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments may be implemented. Many modifications to the depicted environment may be made by those skilled in the art without departing from the scope of the invention as recited by the claims.

Distributed data processing environment 100 includes server computer 104 and client computing device 108, both interconnected over network 102. Network 102 can be, for example, a telecommunications network, a local area network (LAN), a wide area network (WAN), such as the Internet, or a combination of the three, and can include wired, wireless, or fiber optic connections. Network 102 can include one or more wired and/or wireless networks that are capable of receiving and transmitting data, voice, and/or video signals, including multimedia signals that include voice, data, and video information. In general, network 102 can be any combination of connections and protocols that will support communications between server computer 104, client computing device 108, and other computing devices (not shown) within distributed data processing environment 100.

Server computer 104 can be a standalone computing device, a management server, a web server, a mobile computing device, or any other electronic device or computing system capable of receiving, sending, and processing data. In other embodiments, server computer 104 can represent a server computing system utilizing multiple computers as a server system, such as in a cloud computing environment. In another embodiment, server computer 104 can be a laptop computer, a tablet computer, a netbook computer, a personal computer (PC), a desktop computer, a personal digital assistant (PDA), a smart phone, or any programmable electronic device capable of communicating with client computing device 108 and other computing devices (not shown) within distributed data processing environment 100 via network 102. In another embodiment, server computer 104 represents a computing system utilizing clustered computers and components (e.g., database server computers, application server computers, etc.) that act as a single pool of seamless resources when accessed within distributed data processing environment 100. Server computer 104 includes data analysis application 106.

Client computing device 108 can be a desktop computer, a laptop computer, a tablet computer, a specialized computer server, a smart phone, or any programmable electronic device capable of communicating with various components and devices within distributed data processing environment 100, via network 102. In general, client computing device 108 represents any programmable electronic device or combination of programmable electronic devices capable of executing machine readable program instructions and communicating with server computer 104 and other computing devices (not shown) within distributed data processing environment 100 via a network, such as network 102. Client computing device 108 includes data analysis application 110, database 112, data overlay mechanism 114, and application programming interface (API) 116.

Data analysis application 106 and data analysis application 110 are each one of a plurality of applications known in the art as information graphics software for data visualization, i.e., analyzing and graphically displaying data. Examples of data analysis applications include spreadsheets and presentation software, as well as any software used to graph or analyze potentially large sets of numbers. In an embodiment where server computer 104 is a web server, data analysis application 106 can be a web application.

Database 112 resides on client computing device 108. In another embodiment, database 112 can reside on server computer 104 or elsewhere in the environment. A database is an organized collection of data. Database 112 can be implemented with any type of storage device capable of storing data and configuration files that can be accessed and utilized by client computing device 108, such as a database server, a hard disk drive, or a flash memory. In other embodiments, database 112 can represent multiple storage devices within client computing device 108. Database 112 stores data used by data analysis application 106 and data analysis application 110.

Data overlay mechanism 114 resides on client computing device 108. In another embodiment, data overlay mechanism 114 can reside elsewhere in the environment provided the mechanism can communicate with a data analysis application, such as data analysis application 106 or data analysis application 110. Data overlay mechanism 114 is a mechanism that aids a user in understanding and interpreting information. Data overlay mechanism 114 presents a data interpretation viewport, also known as a widget or lens, which appears to float on top of a potentially complex information space, such as a graph, and reveals insights about the data displayed underneath the widget. Data overlay mechanism 114 enables simplification of the information space. A user can manipulate data overlay mechanism 114 to show varying data points and also to further interpret or visualize the data points. In the depicted embodiment, data overlay mechanism 114 is a standalone mechanism that uses API 116 to interact with data analysis application 106, on server computer 104, and with data analysis application 110, on client computing device 108. In the embodiment, using API 116, data overlay mechanism 114 can control the display of data based on location and size coordinates of the widget. In another embodiment, data overlay mechanism 114 can be integrated within an application, such as data analysis application 106 or data analysis application 110 for manipulation by a user. Data overlay mechanism 114 is depicted and described in further detail with respect to FIG. 2.

API 116 provides an interface between data overlay mechanism 114 and data analysis applications, such as data analysis application 106 and data analysis application 110. An API is a particular set of rules and specifications that a software program can follow to access and make use of the services and resources provided by another particular software program that implements the API. An API serves as an interface between different software programs and facilitates their interaction. API 116 may inform a data analysis application, such as data analysis application 106 or data analysis application 110, of the presence of data overlay mechanism 114, as well as whether to de-emphasize data in the display. API 116 may also interface with data overlay mechanism 114 to determine what data the data analysis application displays.

FIG. 2 is a flowchart depicting operational steps of data overlay mechanism 114, on client computing device 108 within distributed data processing environment 100 of FIG. 1, for displaying and interpreting graphical data, in accordance with an embodiment of the present invention.

Data overlay mechanism 114 receives coordinates (step 202). Prior to initializing data overlay mechanism 114, a user initializes a data analysis application, such as data analysis application 106 or data analysis application 110, and graphical data is displayed on a screen or other display device associated with client computing device 108. When either a user of client computing device 108 or a data analysis application initializes data overlay mechanism 114, the user can manipulate both the size and position of the widget displayed on the screen with the graphical data. The X-Y coordinates of the widget on the screen determine a portion of the graph with which data overlay mechanism 114 interacts. The width of the widget determines a number of “columns” of a graph with which data overlay mechanism 114 interacts, depending on the attributes of the graph on which the widget is overlaid. In one embodiment, a default exists for the size and position coordinates of the widget, and a user can alter the coordinates once the widget is displayed. A user can “stretch” and “shrink” the widget to change the range of data displayed by data overlay mechanism 114, as depicted with respect to FIGS. 3A-3D. Data overlay mechanism 114 receives the coordinates of both position and size from the user's placement of the widget on the screen. In one embodiment, data overlay mechanism 114 includes a toggle button with which the user can change the widget from overlaying a column of data to overlaying a row of data by rotating the widget ninety degrees. In an embodiment where client computing device 108 includes a touch screen, a user can change the size or position of the widget on the screen by swiping the screen with the user's fingers. In one embodiment, API 116 retrieves the coordinates of data overlay mechanism 114 upon initialization and communicates the coordinates to data analysis application 110.

Data overlay mechanism 114 retrieves data (step 204). Data overlay mechanism 114 retrieves the data from data analysis application 110. In another embodiment, data overlay mechanism 114 retrieves data from another data analysis application, such as data analysis application 106. The retrieved data is the full dataset that the data analysis application displays. For example, if data analysis application 110 displays a graph, then data overlay mechanism 114 retrieves all the data within the graph. In one embodiment, API 116 retrieves the data and passes it to data overlay mechanism 114.

Data overlay mechanism 114 de-emphasizes data points (step 206). Data overlay mechanism 114 de-emphasizes all the displayed data points except for the data points that reside in the area the widget overlays. In one embodiment, data overlay mechanism 114 dims the data points that the widget does not overlay such that the de-emphasized data remains visible to the user, but not distracting. In another embodiment, data overlay mechanism 114 removes the data points from the view of the graph. In one embodiment, data overlay mechanism 114 controls the display of the data directly and de-emphasizes the data points. In another embodiment, data overlay mechanism 114 instructs data analysis application 110 to de-emphasize the data points. In a further embodiment, API 116 instructs data analysis application 110 to de-emphasize the data points.

Data overlay mechanism 114 receives mode selection (step 208). Data overlay mechanism 114 can operate in a plurality of modes. In one embodiment, the default mode is “Reveal.” When data overlay mechanism 114 is in Reveal mode, the mechanism reveals the data points that reside within the coordinates of the widget, i.e., the data points the widget overlays. Data overlay mechanism 114 includes one or more modes that include a mathematical function. For example, data overlay mechanism 114 may include a mode called “Average” which averages the data points that reside in the area overlaid by the widget. A user of client computing device 108 selects the desired mode. For example, data overlay mechanism 114 may include a dropdown box on the widget that the user can click on to choose a mode. Modes may appear in a list or a user can type in a mode. In another example, if data overlay mechanism 114 is integrated into the data analysis application, then the tool bar of the data analysis application can include a mode selection option. In one embodiment, API 116 receives the mode selection and passes the mode selection to data overlay mechanism 114.

Data overlay mechanism 114 determines whether the selected mode includes a function (decision block 210). As discussed with respect to step 208, data overlay mechanism 114 includes one or more modes that include a mathematical function. Examples of functions include arithmetic operations such as addition, subtraction, multiplication, and division, as well as more advanced operations such as average, sum, maximum, minimum, percentage, etc. In addition, data overlay mechanism 114 may include one or more functions that the data analysis application can perform, such as a formula or an algorithm. In one embodiment, API 116 determines whether the selected mode includes a function and informs data overlay mechanism 114.

If data overlay mechanism 114 determines the mode includes a function (“yes” branch, decision block 210), then the mechanism performs the function (step 212). If the user selected a mode with a function, then data overlay mechanism 114 performs the function on the data points that reside in the area within the coordinates of the widget. For example, if the selected mode is average and the widget overlays two columns of data in a graph, then data overlay mechanism 114 calculates the average of data points from the two columns that reside in a same row of the graph. In one embodiment, API 116 passes the data to be processed from data analysis application 110 to data overlay mechanism 114 and retrieves the processed data from data overlay mechanism 114 after the mechanism performs the function.

Responsive to performing the function, or if data overlay mechanism 114 determines the mode does not include a function (“no” branch, decision block 210), then the mechanism displays the data (step 214). In one embodiment, data overlay mechanism 114 displays the data that is passed to the mechanism from data analysis application 110. In another embodiment, data overlay mechanism 114 instructs data analysis application 110 to display the data. In a further embodiment, API 116 receives the data from data overlay mechanism 114 and instructs data analysis application 110 to display the data. Data overlay mechanism 114 displays the data points that reside in the area the widget overlays, whether they are the original retrieved data points or the data that results from performing a function on the original retrieved data points. In one embodiment, data overlay mechanism 114 may display the data in a manner that indicates to the user that additional functionality is available. For example, data overlay mechanism 114 may display a particular data point underlined within the view of the widget. The underline can indicate to a user that if the user clicks on the underlined data point displayed in the widget, then data overlay mechanism 114 can interact with the data analysis application to take the user to the origin of the data point within the data analysis file. For example, if the widget resides on top of a graph displayed in a spreadsheet, and data overlay mechanism 114 displays a data point with an underline, then the user can click on the data point, and the mechanism can jump to the cell where the raw data that makes up the graph resides. In another embodiment, data overlay mechanism 114 may display additional functionality by displaying a pop-up box or a dropdown box.

Responsive to displaying the data, data overlay mechanism 114 determines whether new coordinates are received (decision block 216). If a user manipulates the widget by moving the widget to a different position on the screen, or by stretching or shrinking the width of the widget, then data overlay mechanism 114 receives another set of coordinates. If data overlay mechanism 114 receives new coordinates (“yes” branch, decision block 216), then the mechanism returns to step 206 to de-emphasize a new set of data points.

If data overlay mechanism 114 does not receive new coordinates (“no” branch, decision block 216), then the mechanism determines whether a new mode selection is received (decision block 218). A user may perform one or more additional functions on selected data points while viewing a graph in order to perform an analysis. If data overlay mechanism 114 receives a new mode selection (“yes” branch, decision block 218), then the mechanism returns to step 210 to determine whether the new mode includes a function. If data overlay mechanism 114 does not receive a new mode selection (“no” branch, decision block 218), then the mechanism completes execution.

FIGS. 3A through 3D illustrate examples of data displayed using data overlay mechanism 114, on client computing device 108 within distributed data processing environment 100 of FIG. 1, in accordance with an embodiment of the present invention.

FIG. 3A depicts graph 300 as a data analysis application, such as data analysis application 106 or data analysis application 110, displays the graph before a user initiates data overlay mechanism 114. Graph 300 is an example graph that displays headcount data for three different divisions of a company across several years. Column 302 displays the headcount data for 2015. Column 304 displays the headcount data for 2016. Data points for additional years are also displayed. Graph 300 is depicted as a line graph. Data overlay mechanism 114 operates with a plurality of tabular and graph types, including, for example, line charts, bar charts, scatter plots, etc.

FIG. 3B depicts graph 300, as depicted in FIG. 3A, with an example of a widget associated with data overlay mechanism 114 shown. Widget 310 overlays the data points in column 304. Mode indicator 312 shows the current mode for data overlay mechanism 114. In the example, mode indicator 312 shows the current mode is “Reveal,” thus the data points shown in FIG. 3B for column 304 are the same as the data points shown in FIG. 3A. Mode changer 314 is an indicator of a dropdown box. When a user clicks on mode changer 314, data overlay mechanism 114 displays a list of available modes. In one embodiment, in addition to a list of modes, mode changer 314 includes a window in which the user can type in a function, such as a formula. Size changer 316 enables a user to change the size of widget 310 to encompass more or less data columns by, for example, clicking and dragging the ends of the “ruler” markings within size changer 316. In another example, if client computing device 108 includes a touchscreen, a user may change the size of the widget by spreading or narrowing the widget with the user's fingers on the screen. In the depicted embodiment, data overlay mechanism 114 displays each data point in widget 310 with an underline, indicating that further drill down is available on the data. For example, a user may click or tap on an underlined data point, and data overlay mechanism 114 changes the displayed screen to a screen or tab within data analysis application 110 that includes the origin of the data point in graph 300.

FIG. 3C depicts graph 300, as depicted in FIG. 3A, with an example of the widget associated with data overlay mechanism 114 shown. In FIG. 3C, widget 310 overlays the data points in column 302 and column 304. In the example, mode indicator 312 shows the current mode is “Reveal,” thus the data points shown in FIG. 3C for both column 302 and column 304 are the same as the data points shown in FIG. 3A. Size changer 316 is larger, with respect to FIG. 3B, because the user widened widget 310 to include two columns of data.

FIG. 3D is similar to FIG. 3C, however in the current example, mode indicator 312 shows the current mode is “Average,” thus the data points which data overlay mechanism 114 displays, via widget 310, are the average of the data points which data overlay mechanism 114 displays in column 302 and column 304 of FIG. 3C. In the example, the data points are not underlined, as the average which data overlay mechanism 114 displays is the result of an applied analytic, and therefore no further drill down is available.

FIG. 4 depicts a block diagram of components of client computing device 108, executing data overlay mechanism 114, within distributed data processing environment 100 of FIG. 1, in accordance with an embodiment of the present invention. It should be appreciated that FIG. 4 provides only an illustration of one implementation and does not imply any limitations with regard to the environments in which different embodiments can be implemented. Many modifications to the depicted environment can be made.

Communications fabric 402 provides communications between cache 414, memory 406, persistent storage 408, communications unit 410, and input/output (I/O) interface(s) 412. Communications fabric 402 can be implemented with any architecture designed for passing data and/or control information between processors (such as microprocessors, communications and network processors, etc.), system memory, peripheral devices, and any other hardware components within a system. For example, communications fabric 402 can be implemented with one or more buses.

In this embodiment, persistent storage 408 includes a magnetic hard disk drive. Alternatively, or in addition to a magnetic hard disk drive, persistent storage 408 can include a solid-state hard drive, a semiconductor storage device, a read-only memory (ROM), an erasable programmable read-only memory (EPROM), a flash memory, or any other computer readable storage media that is capable of storing program instructions or digital information.

The media used by persistent storage 408 may also be removable. For example, a removable hard drive may be used for persistent storage 408. Other examples include optical and magnetic disks, thumb drives, and smart cards that are inserted into a drive for transfer onto another computer readable storage medium that is also part of persistent storage 408.

Communications unit 410, in these examples, provides for communications with other data processing systems or devices, including resources of server computer 104. In these examples, communications unit 410 includes one or more network interface cards. Communications unit 410 may provide communications through the use of either or both physical and wireless communications links. Data analysis application 110, database 112, data overlay mechanism 114, and API 116 may be downloaded to persistent storage 408 through communications unit 410.

I/O interface(s) 412 allows for input and output of data with other devices that may be connected to client computing device 108. For example, I/O interface(s) 412 may provide a connection to external device(s) 416 such as a keyboard, a keypad, a touch screen, a microphone, a digital camera, and/or some other suitable input device. External device(s) 416 can also include portable computer readable storage media, for example, devices such as thumb drives, portable optical or magnetic disks, and memory cards. Software and data used to practice embodiments of the present invention, e.g., data analysis application 110, database 112, data overlay mechanism 114, and API 116 can be stored on such portable computer readable storage media and can be loaded onto persistent storage 408 via I/O interface(s) 412. I/O interface(s) 412 also connect to a display 418.

Display 418 provides a mechanism to display data to a user and may be, for example, a computer monitor. Display 418 can also function as a touchscreen, such as a display of a tablet computer.
